MEANS FOR MOUNTING CURRENT-DISTRIBUTER BLOCKS.

Patented Jan. 218, 1919.

Application filed October 19, 1917. Serial No. 197,442.

To all whom it may concern:

Be it known that I, SAMUEL C. MoKnowN, a citizen of the United States, residing at East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Means for Mounting Current Distributer Blocks, of which the following is a specification.

The object of this invention is to' rovide means of mounting a distributer bloc on an ignition apparatus, as for example a mag neto, in such a way that the block willbe held securely in place, at the same time permitting the holding on means to be quickly removed so that the block can be taken oii the i of inspection,

There ition machine for the purpose etc. have been numerous arrangements proposed and used in the ast for holding distributer blocks on to ignltion devices but where such ignition devices are placed on multi-cylinder engines used in connection with hydro and aeroplanes it has been found that, due to the excessive vibration, the means used heretofore for holding thedistributer blocks on ignition apparatus, such as magnetos, has been found to be inadequate; as it has been determined in actual service that wherever there is a chance for the slightest movement of the distributer blocks, that they begin to wear and in a short time become so loose on their fittings or supports as to require replacement sometimes of the whole machine, due to the fittings themselves becoming loose and worn.

My present invention is directed to ways and means of holding distributor blocks on ignition machines used in the service above described. I aim to mount the block on the supporting plate so that there is no radial movement, no longitudinal and no trans verse motion and I provide means for securing the holding means so that they cannot possibly et out of normal working position, all of which will be hereinafter pointed out,

In the drawing, Figure 1 illustrates a side elevation of a magneto showing the distributer block in working position with a part of the holding means in view.

Fig. 2 is an end elevation of Fig. 1.

Fig. 3 is an enlarged perspective section of the block and support plate at the location of one of the holding means as shown in Fig. 1 but with the spring member redistributer block to the support shown at 4;. On the end plate 2 a distributor block 5 is adapted to be mounted. Holes 6 are shown in the block 5 for the purpose of bringin out the secondary leads running to the spar plugs. Attached to the end plate 2 is a resilient member shown in Fig.

and an alternative method for hold-.

4 in the form of a fiat spring 7, one end of which is turned over at 8 to receive a pin 9 that is suitably mounted in the end plate 2. The spring 7 has a bow 10 in order to give considerable resiliency to the outer end which has a hole 11, preferably oblong. The plate 2 has a rim 12, shown in Fig. 3, and the block 5 has an annular shoulder 13 adapted to closely fit under the rim 12, thus preventing radial motion of the block. Securely fastened to the block 5 are studs 14 preferabl of metal and rectangular in shape and terminating in projections 15 somewhat conical or acorn shaped, that is to say, the ends 15 have grooves 16 slightly smaller than the ends 15 so that the holes 11 in spring members 7 Will'snap over the ends ,15 into the grooves 16 and due to the tension pro- By transverse motion I mean motion at right angles to the cars 18. The exact size and shape of the slots 17 and the studs 14 may be varied considerably from thatfshown so long as they vent any rotary movement of the block 5.

Attached to the ears l8 arebosses 19 through which the cotter pin 20 is adapted to pass, thesame being put into position as shown in Fig. 1 after the spring members 7 are cotiperate to absolutely prea ing the spring 7 in position, it will be apparent that other means maybe provided, or in some cases thesprings v7 may be dispensed with entirely by using pins 21, shown in Fig. 3, which can be readily removed for taking off the block 5. In this modified construction the pins 21 pass through the ears l8 and the lugs 1-4. As a further precaution to hold the block 5 securely in place a combination of the springs 7 and pins 21 may be used so that if the springs 7 should break for any reason the pins 21 will still hold the block 5 .in position. Various other changes and alterations may be made in the details relating to my invention without departing from the spirit of the same or the scope of the appended claims.

Having thusdescribed my invention what I claim is 1.
